If you transport Insulating Glass units from low to high altitudes, or vice versa, install these CRL Capillary Tubes into the spacer frame to equalize pressure. The smaller inside diameter of the Tube and longer length does not allow as much moisture to travel up the Tube. At the destination point the Tube does not have to be crimped and sealed, just bent over along the frame at the top of the unit.

Most shipping weights are approximate and have not been verified. If the exact weight is needed in order to determine shipping costs, and shipping costs are required in order for you to complete your order, please request this prior to submitting your order by contacting CRL Customer Service. Product images shown are of the actual product or a close representation. ColorsColours can vary depending on your computer's video card and on how your monitor's colorcolour is adjusted.
